This is a continuation-in-part of U.S. patent application Ser. No. 889,255, filed July 25, 1986.

BACKGROUND OF THE INVENTION

This invention relates to novel 3(2H)-pyridazinone derivatives, process for preparation thereof, and insecticidal compositions containing said derivatives as an active ingredient.

The present inventors have previously found that a part of the compounds of the general formula (IV) below has insecticidal, acaricidal, nematicidal, fungicidal activities for agricultural and horticultural uses (refer to European Laid-open Patent Publication No. 0,088,384): ##STR5## wherein R' represents, for example, an alkyl; A' represents a halogen; and R³ and R⁴ represent hydrogen or a lower alkyl.

One of the main features of these known compounds resides in that R' is an alkyl. On the other hand, British Pat. No. 917,849 Publication discloses 3(2H)-pyridazinone derivatives of the formula (V): ##STR6##

This publication also discloses that the known compound A below is included in the compounds of the formula (V). ##STR7##

However, both the two phenyl rings in the compound A are unsubstituted. Moreover, there is no description in this publication as to the use for an insecticide that is intended in the present invention although the publication disclosed that the compounds A are used for agricultural drugs which affect the growth of plants.

In addition, Japanese Patent Publication No. 09344/67 discloses 3(2H)-pyridazinone derivatives of the formula (VI): ##STR8## wherein R⁷ represents, for example, benzyl or 4-chlorobenzyl.

One of the main features of these known compounds (VI), however, resides in that the compounds have a thioether group. Moreover, there is not described such compounds wherein both the two phenyl rings are substituted. The physiological activities described therein are restricted to fungicidal activity and central nerve-depressive activity. Thus, the compounds (VI) are apparently different from the compounds according to the present invention.

An object of the present invention is to provide novel 3(2H)-pyridazinone derivatives.

Another object of the invention is to provide a process for preparing such novel 3(2H)-pyridazinone derivatives.

Still another object of the invention is to provide insecticidal compositions containing such novel 3(2H)-pyridazinone derivatives as an active ingredient.

Still further object of the invention is to provide a method for insecticidal treatment in the agricultural and horticultural field with the effective amount of a compound of the formula (I).

DETAILED DESCRIPTION OF THE INVENTION

The novel 3(2H)-pyridazinone derivatives according to the present invention are represented by the general formula (I): ##STR9## wherein X represents a halogen, an alkyl having 1 to 6 carbon atoms, a haloalkyl having 1 to 4 carbon atoms, a haloalkoxy having 1 to 4 carbon atoms, nitro, an alkoxy having 1 to 4 carbon atoms or ##STR10## (wherein R represents an alkyl having 1 to 4 carbon atoms); n is an integer of from 1 to 4;

R¹ and R² represents each independently hydrogen or an alkyl having 1 to 4 carbon atoms;

E represents hydrogen, a halogen, an alkoxy having 1 to 4 carbon atoms or hydroxyl; and Q represents ##STR11## (wherein Y represents a halogen, an alkyl having 1 to 6 carbon atoms, an alkoxy having 1 to 6 carbon atoms, a haloalkyl having 1 to 4 carbon atoms, a haloalkoxy having 1 to 4 carbon atoms, cyano, ##STR12## (wherein Z represents a halogen, an alkyl having 1 to 4 carbon atoms, an alkoxy having 1 to 4 carbon atoms or a haloalkyl having 1 to 4 carbon atoms; and is 0 or an integer of from 1 to 5, said Z being the same or different when is an integer of from 2 to 5); and m is an integer of from 1 to 5, said Y being the same or different when m is an integer of from 2 to 5), said X being the same different when n is an integer of from 2 to 4.

The present inventors have conducted intensive researches on insecticidal activity of the novel 3(2H)-pyridazinone derivatives of the formula (I) described above and have found that the compounds of the invention have excellent and effective activities for the control of insect pests to accomplish the present invention.

The compounds of the invention are quite different from conventional insecticides in that they exhibit extremely strong and specific action against a certain kind of insect pests and also have excellent residual action to exhibit highly effective control of insect pests.

Namely, the compounds according to the invention strongly disturb physiological process of transformation (metamorphosis) and casting off (ecdysis) of insect pests caused by insect hormone to malform the insect pests and inhibit casting off thereof, being totally different from conventional drugs which act on the nervous systems of insect pests, such as organic chlorine-insecticides, organic phosphorus-insecticide, carbamate-insecticides and pyrethroide insecticides of the prior art. Such inhibition of casting off causes some pests to die and thus, together with the excellent residual action of the present compounds, the compounds of the invention exhibit highly effective control of insect pests.

Such selective control, unlike prior art methods, is very useful for protecting cultivated crops without destroying an ecosystem, because of very small effects on natural enemies against insect pests including predatory mites (e.g., Amblyseius longispinosus) and also on useful insects. Moreover, the compounds of the invention are excellent in safety because of low toxicity to warm-blooded animals and fish.

Among the compounds of the present invention, following compounds are preferable in respect to insecticidal activities.

Compounds of the general formula (IA): ##STR13## wherein E represents hydrogen, chlorine or methoxy; A represents hydrogen, chlorine, bromine, fluorine, iodine or methyl; B represents nitrogen or CX₁ (wherein X₁ represents hydrogen or a halogen); X represents a halogen, and alkyl having 1 to 4 carbon atoms, and alkoxy having 1 to 4 carbon atoms, NO₂, CO₂ R (wherein R represents an alkyl having 1 to 4 carbon atoms) or a haloalkoxy having 1 to 4 carbon atoms; n is an integer of from 1 to 4; Q represents: ##STR14## Y represents a halogen, an alkyl having 1 to 4 carbon atoms, a haloalkyl having 1 to 3 carbon atoms, haloalkoxy having 1 to 3 carbon atoms or an alkoxy having 1 to 4 carbon atoms; and m is an integer of from 1 to 5, said X being the same or different when n is an integer of from 2 to 4 and said Y being the same or different when m is an integer of from 2 to 5.

More preferred are those represented by the Formula (IB): ##STR15## wherein E represents hydrogen; A represents hydrogen, chlorine, bromine, fluorine or iodine; X₂ represents a halogen, hydrogen or nitro; X₃ and X₄ represents each independently hydrogen, a halogen, nitro or an alkyl having 1 to 3 carbon atoms; Q represents: ##STR16## Y represents a halogen or a haloalkyl having 1 to 3 carbon atoms; and m is an integer of 1 or 2, and Y being the same or different when m is 2.

Particularly preferred are the compounds of the formula (IC): ##STR17## wherein E represents hydrogen; A represents chlorine, bromine, fluorine or iodine; X₅ represents hydrogen, halogen or nitro; X₆ represents hydrogen, nitro or halogen; Q represents ##STR18## Y₁ represents a halogen; and Y₂ represents hydrogen or a halogen.

More specifically, among the compounds listed in Table 1-a and 1-b given later, preferable compounds are shown in Table 6. Among them, the most preferable compounds are Nos. 340, 341, 393, 507, 508, 582, 583, 607 and 608.

The compounds of the invention can be produced according to the following reaction: ##STR19## wherein R¹, R², A, B, E, X, Q and n are defined above, and X' and X" represent a halogen or --OM (wherein M represents hydrogen or an alkali metal), provided that X" represents a halogen when X' is --OM and X" represents --OM when X' is a halogen.

More specifically, the compounds of the invention can be prepared according to the following Reaction (1) or (2). ##STR20##

In the Reaction (1) and (2), R¹, R², A, B, E, X, Q, M and n are as defined above and hal represents a halogen.

The compounds of the invention can be produced by reacting one of the starting materials, a 3(2H)-pyridazinone derivative of the formula (VII) or (IX) above, with another starting compound of the formula (VIII) or (X) above in an appropriate solvent in the presence of a hydrogen halide-absorbing agent. It should be noted, however, that the hydrogen halide-absorbing agent is not always required when M represents an alkali metal.

As the solvent can be used lower alcohols such as methanol, and ethanol; ketones such as acetone and methylethyl ketone; hydrocarbons such as benzene and toluene, ethers such as isopropyl ether, tetrahydrofuran and 1,4-dioxane; amides such as N,N-dimethyl-formamide and hexamethyl phosphoric triamides; and halogenated hydrocarbons such as dichloromethane and dichloroethane. As necessary, these solvents can be used as a mixture with water.

As the hydrogen halide-absorbing agent can be used inorganic bases such as sodium hydride, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate and sodium bicarbonate; and organic bases such as sodium methoxide, sodium ethoxide, triethylamine and pyridine. As necessary, there may be added to the reactive system a catalyst such as tetraammonium salts (e.g., triethylbenzylammonium chloride).

The reaction temperature ranges from -20° C. to the boiling point of the solvent to be used in the reaction. However, the reaction temperature in the range of from -5° C. to the boiling point of the solvent used is desirable.

The molar ratio of the starting materials can be optionally selected. However, it is advantageous to conduct the reaction using equimolar or nearly equimolar amount of the materials.

Incidentally, the compounds of the formula (IX) above can be prepared by a process according to the following reaction: ##STR21## wherein X, A, B, E, M, n and hal are as defined in the above and R³ represents methyl or ethyl.

The compounds encompassed by the present invention are illustrated by the compounds listed in Tables 1-a and 1-b below. However, it should be understood that the compounds in Tables 1-a and 1-b are merely illustrated and not to restrict the invention.

The compounds of the invention exhibit specific insecticidal action on hemiptera insects such as planthopper and leafhopper; Coleoptera insects such as red flour beetle (Tribolium castaneum), yellow mealworm (Tenebrio molitor) and 28-spotted lady beetle (Henosepilachna vigintioctopunctata); sanitary insect pests such as flies and mosquitos; and lepidoptera insects and also exhibit excellent residual action. Thus, the compounds of the invention provide an excellent insecticide which exhibits highly effective control of insect pests.

In the following, the effects of the present compounds as an insecticide are explained in detail by way of the test examples.

TEST EXAMPLE 1 Insecticidal Test on Green Rice Leafhopper (Nephotettix cincticeps)

A 10% emulsifiable concentrate (or a 10% wettable powder) of a compound of the invention was diluted with water containing a spreader to give a 500 ppm solution of the compound. The stems and leaves of rice-plant in a 1/20000 are pot were sufficiently applied with the resulting solution and then air-dried. Thereafter, 20 second instar green rice hoppers (Nephotettix cincticeps) which resist organic phosphorous insecticides and carbamate insecticides were released in the pot.

The rice-plant thus treated was covered with a cylindrical wire gauze and kept in a thermostatic chamber. Thirty (30) days after, the number of the green rice leafhopper parasitic on the rice-plant was counted and the mortality thereof was determined according to the following equation: ##EQU1##

The test was conducted twice for each compound. The results thereof are shown in Table 2.

TEST EXAMPLE 2 Insecticidal Test on Brown Rice Planthopper (Nilaparvata lugens)

The procedures in Test Example 1 were repeated by using second instar brown rice planthoppers (Nilaparvata lugens) instead of the second instar green rice leafhoppers which resist organic phosphorous insecticides and carbamate insecticides. The results thereof are shown in Table 3.

TEST EXAMPLE 3 Insecticidal Test on Red Flour Beetle (Tribolium castaneum)

In a transparent spitch tube was placed 50 mg of a 10% emulsifiable concentrate of a compound of the invention (or a 10% wettable powder or a 10% oil solution thereof), and thereto was added acetone to give a 500 ppm acetone solution of the compound. Ten (10) cc of the acetone solution was added to 10 g of wheat flour placed in a laboratory dish of 9 cm in diameter. After stirring acetone was distilled away from the mixture. Then, 10 adults each of male and female red flour beetles (Tribolium castaneum) were released in the dish. The dish containing the adults was kept in a thermostatic chamber. Ninety days after, evaluation was conducted by counting the number of the adults which came out.

The test was conducted twice for each compound. As a result, no hatched adult was observed at all in the dish treated with any one of the following compounds: Compound Nos. 27, 28, 175, 235, 283, 342, 584, 827, 828, 829, 830, 831, 834, 835, 837, 839 and 858.

TEST EXAMPLE 4 Fish-toxicity test on killifish

A methanol solution containing a compound of the invention to be tested is added to 2 l of water in a glass vessel of 20 cm in diameter and 10 cm in height to give a 0.5 ppm solution of the compound. The vessel was kept in a thermostatic chamber at 25° C. and then 10 killifishes were placed therein. The fish was observed with the passage of time. The mortality thereof after 48 hours is shown in Table 4.

TEST EXAMPLE 5 Acute Oral Toxicity Test to Mammals

ICR (Swiss Hauschka, CD-1, Ha/ICR) male mice were obtained at 4 weeks old from Clea Japan, Inc., and used in the tests after an acclimatizing period of one week. The animals in groups of 5 were housed in stainless cages with a wire-meshed bottom. The animals rooms were sustained in a barrier system with a controlled temperature of 22°±1° C., humidity of 55±5% and light for 12 hours a day. The animals were supplied food (CE-2, Clea Japan, Jinc.) and tap water ad libitum, Groups of 5 animals were administered a single oral dose of 300 mg/kg of the present inventional compound by oral gavage. The compounds were diluted by corn oil, and all administration volumes were 10 ml/kg body weight. The mortalities were calculated seven days after oral administration. The result was shown in Table 5.

TEST EXAMPLE 6 Insecticidal Test on Almond Moth (Ephestia cautella)

In a transparent spitch tube was placed 50 mg of a emulsifiable concentrate of a compound of the invention (or a wettable powder or an oil solution thereof), and thereto was added acetone to give a 500 ppm acetone solution of the compound. Ten (10) cc of the acetone solution was added to 10 g of rice bran placed in a laboratory dish of 9 cm in diameter. After stirring acetone was distilled away from the mixture. Then, 10 larvae each of almond moth (Ephestia cautella) were released in the dish. The dish containing the larvae was kept in a thermostatic chamber. 30 days after, evaluation was conducted by counting the number of the adults which came out.

The test was conducted twice for each compound. As a result, no hatched adult was observed at all in the dish treated with any one of the following compounds: Compound Nos. 340, 341, 342, 584, 590, 778, 802, 827, 828, 829, 831, 834, 837 and 858.
